finished implementing new Task Manager; separated it out from the App Manager

added "press and hold" Home button gesture for pulling up the Task Manager

going to wire up the Settings UI to the mozSettings interface over the next day or so

considering abstracting out the animation/drawing logic used for the Task Manager to improve the "app launch" and "app close" animations instead of them relying on scaling the "live" IFRAME; the Task Manager uses -moz-element to draw the app IFRAME's contents to the background-image of another element and the animations performed with those elements seem to have a much better performance/frame rate

created the beginnings of the "Market" app several weeks ago but haven't integrated the code in yet; would like to do this over the next week as well
